LOCKING DEVICE FOR CABINETS.

Specification of Letters Patent.

Patented June e, 1920.

Original application filed May 31, 1916 Serial No. 100,921. Divided andthis application filed January To all whom, it may concern:

Be it known that I, FRANK H. Honnnc, citizen of the United States,residing at Green Bay, county of Brown, and State of Wisconsin, haveinvented new and useful Improvements in Locking Devices for Cabinets, ofwhich the following is a specification.

This application is a division of my former application for LettersPatent for paper feeding cabinets, filed May 31, 1916, Serial No.100,921, patented Apr. 23, 1918, No. 1,263,669.

The object of the present invention is to provide locking means for acabinet of this type whereby the lid or door of the cabinet may besecured to the body thereof near the upper end by a latch which willautomatically engage and lock the cabinet when the door is closed andwhich latch can only be released by a person familiar with the structureof the latch and of the cabinet, the lock being so arranged that accessto the latch may be had only through the opening or slit through whichthe paper is discharged from the cabinet.

More particularly the object of my invention is to provide a form oflatch for a cabinet of the described class in which the latch may belocated near the upper end of the cabinet and provided with a latchoperating arm extending through suitable guides within the cabinet to apoint near its lower end, whereby access to the operating arm may be hadthrough the discharge opening or slit at the lower end of the cabinet.

In the drawings- Figure 1 is a front elevation of a paper feedingcabinet embodying my invention with portions of the front wall brokenaway to show the interior sheet starting and cabinet locking mechanism.

Fig. 2 is a sectional view of the same drawn on line 2-2 of Fig. 1 butshowing a paper package in position.

Like parts are identified by the same reference characters in bothviews.

The cabinet is preferably constructed in two sections, comprising a backsection A and a cover section B hinged together at C and with the sidewalls of the cover section telescoping over those of the back section.The cover section is provided near its upper end with a hook shapedbracket B and a locking bar A is mounted to slide upon the Serial No.143,244:.

rear wall of the back section and is provided at its upper end with alatch a adapted to engage the hook shaped bracket B when the bar A ispulled downwardly. The lower end of the cabinet is provided with a slot,or left open for the discharge of sheets of paper, and by inserting atool through this lower end of the cabinet, a projection a carried bythe bar A may be engaged and the locking bar manipulated to lockorunlock the cabinet. When unlocked, the cover section may be swungdownwardly upon the hinge pin C to expose the interior.

The package of paper D is supported from a bracket E within the cabinetas described in said former application. The operating lever F, springG, brush H, and guide flanges J therefor are the same in structure andmode of operation as described and claimed in said former applicationand de tailed description herein is therefore deemed unnecessary.

It will be observed that the hook shaped bracket B on the cover sectionhas an upturned inner extremity b. The locking bar A may be convenientlysupported from the back wall by guide pins K at their respective endsand inserted through the back Wall and through slots L in the lockingbar A, the length of the slots limiting the vertical movement of the barA. The latch a, is supported from the upper end of the bar A by ahorizontal arm A which is normally.

at a sufficient distance from the upper end wall of the cabinet to allowa vertical movement of the bar A. substantially equal to the length ofthe slots L whereby the bar A may be pushed upwardly until the arm A andlatch a occupy the dotted line position in which they are illustrated inFig. 2.

In the construction shown, any ordinary tool adapted to enter the lowerend of the cabinet may be used to push the bar A upwardly and releasethe latch a. The character of the tool will, of course, depend upon thespecific form and shape of the cabinet and upon obstructions, if any,within the cabinet between the slotted lower end, and the latchoperating piece a. "Whenever the door is to be closed, the latchoperating bar A will be raised preparatory to closing the door andreleased when the door is fully closed, whereupon the latch a will beautomatically engaged, since the bar A will drop by gravity unlessmanually supported.

It will be understood that when the cabi net is filled the packagevofpaper will be pushed backwardly and will cover the lower end of the barA, but as the paper is with drawn the package will be pushed forwardlyby the feeding spring as described in my guide pins secured through therear wall of the back section, one above the other, a lock ing barhaving longitudinal slots mounted upon said guide pins adapted forvertical reciprocation, a horizontal arm at the upper end of the saidbar with a hooked free end serving as a latch adapted for engaging saidbracket when the bar is in its normal lowered position with the coversection closed,

and an inwardly extending projection upon the lower end of the baradapted for access through said opening for elevating the bar when thecabinet is empty whereby the latch is released during the unlockingoperation.

In testimony whereof I affix my signature 1n the presence of twowitnesses.
